(Id.) Dr. Naeem opined that because of Wilson’s COPD and obesity he was incapable of even low stress jobs. (R. 257.)
ALJ Friedman’s Decision
On June 27, 2Ó13, ALJ Friedman denied Wilson’s claim for benefits. (R. 16-25.) ALJ Friedman followed a five-step analysis, considering Wilson’s testimony and the medical record. (R. 19-21.) At the first step, ALJ Friedman determined that Wilson “has not engaged in súbstantial gainful activity since January 29, 2012, the alleged onset date.” (R. 21.)
At the second step, ALJ Friedman determined that Wilson had “the following severe impairments: Obesity, Chronic Obstructive Pulmonary Disorder, and Orthopedic Pain.” (Id.)
• At the third step, ALJ Friedman determined that Wilson “does not have an impairment or combination of impairments that meets or medically equals the severity of one of the listed impairments in 20 C.F.R. Part 404, Subpart P, Appendix 1.” (R. 21.) ALJ Friedman “considered section[ ] 3.02 of the Listings in particular” in making his finding, stating:
*396An individual of the claimant’s height must have an FEV1 of 1.65 or less to meet Listing 3.02. Here, the claimant’s medical evidence indicates an FEV1 no less than 2.499. Therefore, the claimant’s chronic obstructive pulmonary disorder does not satisfy the requirements of Listing 3.02.
Furthermore, orthopedic pain and obesity are not listed impairments. The undersigned has considered these impairments to the extent that they affect other bodily systems. Here, his pain and obesity do not either singly, or in combination, meet or medically equal any listed impairment.
(R. 21, record citation omitted.)
ALJ Friedman found that Wilson had the RFC “to perform light work as defined in 20 C.F.R. § 404.1567(b) except he is restricted from performing jobs involving pulmonary irritants.” (R. 22.) ALJ Friedman “considered all symptoms and the extent to which these symptoms can reasonably be accepted as consistent with the objective medical evidence and other evidence.” (Id.) He also “considered opinion evidence in accordance with the requirements of 20 C.F.R. § 404.1527 and SSRs 96-2p, 96-5p, 96-6p and 06-3p.” (R. 22.) ALJ Friedman found that Wilson’s medically determinable impairments could reasonably be expected to cause Wilson’s alleged shortness of breath that “ ‘comes and goes’” and chronic pain limiting his ability to work. (R. 22.) However, ALJ Friedman found that Wilson’s statements concerning the intensity, persistence and limiting effects of the symptoms were “not entirely credible.” (R. 22.) In particular, ALJ Friedman wrote:
[Wilson’s] activities suggest that he is not as limited as he has alleged. He engages in a daily routine that includes the walking and caring for dogs. He is able to care for himself and his home. Additionally, his records indicate that he ceased work in March of 2012 through retirement, not as a result of limitations due to his condition.- These facts strongly suggest that the claimant’s allegations are not fully credible.
(R. 23, record citations omitted.) Despite finding Wilson not entirely credible, ALJ Friedman found that Wilson’s orthopedic pain, obesity and COPD limited him to light work without exposure to pulmonary irritants. (Id.)
ALJ Friedman acknowledged that Wilson’s reported lower back, neck and leg pain when standing and walking was supported in the medical records, and that Wilson exhibited positive straight leg raising while supine. (R. 22.) However, ALJ Friedman found this outweighed by Wilson’s appearance and performance in examinations, responsiveness to pain treatments, and normal medical imaging. (Id.) ALJ Friedman highlighted that Wilson “is able to care for himself, including dressing, bathing, cooking meals, and shopping. He is able to travel via train to attend appointments.” (R. 22-23, record citation omitted.)
ALJ Friedman stated that Wilson’s height of seventy-three inches and weight fluctuating around 300 pounds placed him “well within the range of obese.” (R. 23.) ALJ Friedman stated that Wilson’s “records do not indicate any significant complications from his obesity beyond possible contribution to his orthopedic pain.” (Id.) ALJ Friedman noted that Wilson “does not exercise and only ‘tries to watch his diet.’ ”' (Id.)
ALJ Friedman found that Wilson’s medical records indicated that his chronic obstructive pulmonary disorder had been less persistent and limiting than alleged. (Id.) Although ALJ Friedman noted that Wilson had experienced “‘very severe obstruction, with low vital capacity,’ ” and *397had occasional shortness of breath and wheezing, ALJ Friedman noted six examinations where Wilson’s lungs were clear to auscultation without wheezing, rhonehi or rales. (Id.) ALJ Friedman also noted that Wilson’s records stated that he was “ ‘doing well’ ” and was “ ‘stable.’ ” (Id.) Additionally, ALJ Friedman observed that Wilson’s own physician found that he only had “ ‘mild obstructive disease.’ ” (Id.)
ALJ Friedman also relied on Wilson’s objective medical tests: “Furthermore, objective medical tests have shown FEV1 peak flow testing of 3.14, 3.076, 3.532, 2.499, and 3.245. This testing has ranged from 73% to 129% of predicted and normal rates.... This suggests that his condition is not as limiting as alleged.” (Id., record citations omitted.) ALJ Friedman noted Wilson’s walking and caring for dogs, for himself and for his home. (Id.) ALJ Friedman also observed that Wilson’s “records indicate that he ceased work in March of 2012 through retirement, not as a result of limitations due to his condition.” (Id.) ALJ Friedman concluded that “[tjhese facts strongly suggest[ed]” that Wilson’s allegations were “not fully credible.” (Id.)
ALJ Friedman accorded “great weight” to the opinion of state agency reviewer Dr. Bankhead that Wilson is capable of performing light exertional work. (R. 23.) ALJ Friedman noted that Dr. Bankhead “based his opinion on findings from [objective] peak flow testing revealing FEV1 levels in 2012 up to 129% of expected values” and on the fact that'Wilson had a positive straight leg raising test and some limitation in forward flexion. (Id.) ALJ Friedman gave Dr. Bankhead’s opinion great weight because “his opinion’s rationale is explained in great detail” and “is consistent with [Wilson’s] objective medical evidence” despite the fact that Dr. Bankhead is neither a treating nor examining source. (Id.)
ALJ Friedman gave “some weight” to consultative examiner Dr. Revan’s opinion. (R. 24.) ALJ Friedman noted Dr. Revan’s opinion that Wilson had “only ‘mild limitations with walking due to knee pain. Limitations with standing and sitting due to back pain and neck pain [and] mild limitation to climbing stairs due to shortness of breath.’” (Id.) ALJ Friedman noted that Dr. Revan’s opinion did not provide specific limitations on Wilson’s abilities nor specify her opinion as to an appropriate exertional category. (Id.) ALJ Friedman found that Dr. Revan’s opinion was “somewhat consistent with the objective medical evidence, including FEV1 testing,” and was based on an examination of Wilson. (Id.) Dr. Revan’s opinion was given only some weight because it “fail[ed] to give specific limitations or abilities.” (Id.)
ALJ Friedman gave “little weight” to treating physician Dr. Naeem’s opinion that Wilson could stand for only ten minutes, sit for fifteen minutes at a time for a total of two hours, lift no more than ten pounds, had limitations in motion, must avoid exposure to many environmental factors, had an inability to work at even low stress jobs, and would be off-task twenty-five percent of the day. (R. 24.) ALJ Friedman found that Dr. Naeem’s opinion was “inconsistent with the medical evidence as a whole.” (Id.) ALJ Friedman compared Dr. Naeem’s reliance on Wilson’s “fatigue, shortness of breath, orthopnea, and chest tightness” with records that “routinely show [Wilson] to have lungs clear to auscultation,” and concluded that Wilson’s “medical records do not support Dr. Naeem’s opinion.” (Id.) ALJ Friedman also noted Wilson’s reportedly stable condition, “normal FEV1 peak flow testing,” and actual “activities of daily living *398that demonstrate abilities beyond those opined by Dr. Naeem(Id.)
ALJ Friedman also gave “little weight” to treating physician Dr. Husain’s opinion. (R. 24.) ALJ Friedman noted Dr. Husain’s opinion that Wilson could, stand or walk for up to two hours per day, stand for less than six hours per day, and lift only five pounds. (Id.) ALJ Friedman observed that Dr. Husain’s opinion “containfed] no explanation or reference ,of objective medical evidence or tests” and was “merely conclusory in nature.” (Id.) Further, ALJ Friedman noted that “objective medical evidence, including spirometrie testing, reveals that [Wilson’s] conditions, including COPD, are not nearly as limiting as he has alleged.” (Id.) Therefore, ALJ Friedman found Dr. Husain’s opinion to be inconsistent with the medical evidence and not entitled to controlling weight as the opinion of a treating physician. (Id.)
ALJ Friedman did not address Dr. Dob-kin’s medical records. (R. 19-25.)
At the fourth step, ALJ Friedman determined that Wilson “is capable'of performing past relevant work as a Staff-Analyst” as the work “does not require the performance of work-related activities precluded by [Wilson’s] residual functional capacity’.” (R. 24.) In comparing Wilson’s RFC to' his past relevant work, ALJ Freidman found that because Wilson “is able to perform light exertional work and is only precluded from work involving pulmonary irritants ... [Wilson is] capable of returning to his past relevant work as a Staff Analyst.” (R. 25.) ALJ Friedman noted that work as a staff analyst required lifting no more than ten pounds, walking for three hours, standing for two hours, and sitting for two hours during a workday. (Id.) ALJ Friedman also noted that Wilson “did not testify that his work involved work with pulmonary irritants.” (Id.)
ALJ Friedman concluded that Wilson had not been under a disability from January 29, 2012 through the date of his decision, June 27, 2013, and did not continue to step five. (R. 25.)
Additional Evidence Before the Appeals Council
On July 29, 2013, Wilson submitted medical evidence from Dr. Carl Gerardi (spanning the period from April 22, 2008 to May 1, 2013) to the Appeals Council with his request to review ALJ Friedman’s decision. (R. 4, 258-364.)
Dr. Gerardi saw Wilson on numerous occasions for urology-related treatments. (See, e.g., R. 260, 352, 353.) On May 14, 2008, Dr. Gerardi performed a TUNA procedure on Wilson. (R. 352, 362.) On September 8, 2009, Wilson again saw Dr. Gerardi. (R. 288.) Wilson did not report fatigue,' nasal congestion, cough, shortness of breath, wheezing, back pain, joint pain, muscle pain or dizziness. (Id.)
On April 6, 2010, Wilson was examined by Dr. Gerardi. (R. 284,332.) Wilson did not report fatigue, nasal congestion, cough, shortness of breath, wheezing, back pain, joint pain, muscle pain or dizziness. (R. 284, 333.) Wilson reported his height as seventy-three-inches and his weight as 250 pounds, which calculates a BMI of 32.98. (R. 284.) Wilson’s respiration was noted as “[u]nlabored.” (Id.) On physical examination, Dr. Gerardi noted that Wilson was “[n]ot in acute distress” and had “normal respiratory effort” on chest and lung exam. (R. 284-85.) Notes from Wilson’s May 18, June 15, and- September 21, 2010 examinations by Dr, Gerardi are essentially identical. (R. 277,279-80.) . .
On February 20, 2013, Wilson: reported to Dr. Gerardi that he had fatigue, nasal congestion, shortness of' breath; cough, wheezing, chest pain and palpitations, back pain, joint pain, muscle pain and dizziness. *399(R. 271, 311.) Wilson’s height was recorded as seventy-three inches with a weight of 250 pounds and BMI of 32.98. (R. 270.) On Wilson’s patient history form, he reported present medical problems with his back, legs, asthma', obesity and veins. (R. 310.) On physical examination, Dr. Gerardi noted that Wilson was “[n]ot in acute distress” and had “normal respiratory effort” on chest and lung exam. (R. 271-72.) On March 12, 2013, Wilson reported identical symptoms and had identical examination results. ■ (R. 267-68.) On April 4, 2013, Dr. Gerardi completed a physical capacity evaluation for- Wilson, opining that Wilson had no limitations on lifting, and carrying, no limitations on standing or walking, and no limitations on sitting. (R. 297.) On April 10 and on - May 1,2013, Wilson again reported symptoms identical to February 2013 and had identical examination results. (R. 261-62,264-65.)
The Appeals Council’s Decision
On July 8, 2013, Wilson requested Appeals Council review of ALJ Friedman’s decision. (R. 14.) Wilson’s counsel argued that the ALJ had “1. Made no function by function assessment of the [Wilson’s] residual functional capacity. 2. Failed to properly assess [Wilson’s] complaints. 3. Failed to recognize the need for vocational expert testimony- due to his finding that [Wilson’s] ‘chronic obstructive pulmonary disorder mandates that he not work with pulmonary irritants.’ ” (R. 169.) On October 10, 2014, the Appeals Council considered the additional evidence submitted by Wilson, concluded that it did not provide a basis for changing ALJ Friedman’s decision, and denied review. (R. 1-5.) ALJ Friedman’s decision-thus became the Commissioner’s final decision.
ANALYSIS
L THE APPLICABLE LAW
A. Definition Of Disability
A person is considered disabled for Social Security benefits purposes when he is unable “to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected- to result in death or which has lasted or can be expected to last for a continuous period of not less’than 12 months.” 42 U.S.C. §§ 423(d)(1)(A),' 1382e(a)(3)(A); see, e.g., Barnhart v. Thomas, 540 U.S. 20, 23, 124 S.Ct. 376, 379, 157 L.Ed.2d 333 (2003); Barnhart v. Walton, 535 U.S. 212, 214, 122 S.Ct. 1265, 1268, 152 L.Ed.2d 330 (2002); Impala v. Astrue, 477 Fed.Appx. 856, 857 (2d Cir.2012).18
An individual shall be determined to be under a disability only if [the combined effects of] his physical’ or mental impairment or impairments are of such severity that he is not only unable to do his previous work but cannot, considering his age, education, and work experience, engage in any other kind of substantial gainful work which exists in the national economy, regardless of whether such work exists in the immediate area in *400which he lives, or whether a specific job vacancy exists for him, or whether he would be hired if he applied for work.
42 U.S.C. §§ 423(d)(2)(A), 1382c(a)(3)(B); see, e.g., Barnhart v. Thomas, 540 U.S. at 23, 124 S.Ct. at 379; Barnhart v. Walton, 535 U.S. at 218, 122 S.Ct. at 1270; Salmini v. Comm’r of Soc. Sec., 371 Fed.Appx. at 111; Betances v. Comm’r of Soc. Sec., 206 Fed.Appx. at 26; Butts v. Barnhart, 388 F.3d at 383; Draegert v. Barnhart, 311 F.3d at 472.19
In determining whether an individual is disabled for disability benefit purposes, the Commissioner must consider: “(1) the objective medical facts; (2) diagnoses or medical opinions based on such facts; (3) subjective evidence of pain or disability testified to by the claimant or others; and (4) the claimant’s educational background, age, and work experience.” Mongeur v. Heckler, 722 F.2d 1033, 1037 (2d Cir.1983) (per curiam).20
B. Standard Of Review
A court’s review of the Commissioner’s final decision is limited to determining whether there is “substantial evidence” in the record as a whole to support such determination. E.g., 42 U.S.C. § 405(g); Giunta v. Comm’r of Soc. Sec., 440 Fed.Appx. 53, 53 (2d Cir.2011).21 “ ‘Thus, the role of the district court is quite limited and substantial deference is to be afforded the Commissioner’s decision.’ ” Morris v. Barnhardt, 02 Civ. 0377, 2002 WL 1733804 at *4 (S.D.N.Y. July 26, 2002) (Peck, M.J.).22
The Supreme Court has defined “substantial evidence” as “ ‘more than a mere scintilla [and] such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.’ ” Richardson v. Perales, 402 U.S. 389, 401, 91 S.Ct. 1420, 1427, 28 L.Ed.2d 842 (1971); accord, e.g., Selian v. Astrue, 708 F.3d 409, 417 (2d Cir.2013); Rosa v. Callahan, 168 F.3d at 77; Tejada v. Apfel, 167 F.3d at 773-74.23 “[F]actual issues need not have been resolved by the [Commissioner] in accordance with what we conceive to be the preponderance of the evidence.” Rutherford v. Schweiker, 685 F.2d 60, 62 (2d *401Cir.1982), cert. denied, 459 U.S. 1212, 103 S.Ct. 1207, 75 L.Ed.2d 447 (1983). The Court must be careful not to “ ‘substitute its own judgment for that of the [Commissioner], even if it might justifiably have reached a different result upon a de novo review.’ ” Jones v. Sullivan, 949 F.2d 57, 59 (2d Cir.1991).24
The Court, however, will not defer to the Commissioner’s determination if it is “‘the product of legal error.’” E.g., Duvergel v. Apfel, 99 Civ. 4614, 2000 WL 328593 at *7 (S.D.N.Y. Mar. 29, 2000) (Peck, M.J.); see also, e.g., Douglass v. Astrue, 496 Fed.Appx. 154, 156 (2d Cir.2012); Butts v. Barnhart, 388 F.3d 377, 384 (2d Cir.2004), amended on other grounds, 416 F.3d 101 (2d Cir.2005); Tejada v. Apfel, 167 F.3d at 773 (citing cases).
The Commissioner’s regulations set forth a five-step sequence to be used in evaluating disability claims. 20 C.F.R. §§ 404.1520, 416.920; see, e.g., Barnhart v. Thomas, 540 U.S. 20, 24-25, 124 S.Ct. 376, 379-80, 157 L.Ed.2d 333 (2003); Bowen v. Yuckert, 482 U.S. 137, 140, 107 S.Ct. 2287, 2291, 96 L.Ed.2d 119 (1987). The Supreme Court has articulated the five steps as follows:
Acting pursuant to its statutory rule-making authority, the agency has promulgated regulations establishing a five-step sequential evaluation process to determine disability. If at any step a finding of disability or nondisability can be made, the SSA will not review the claim further. [1] At the first step, the agency will find nondisability unless the claimant shows that he is not working at a “substantial gainful activity.” [2] At step two, the SSA will find nondisability unless the claimant shows that he has a “severe impairment,” defined as “any impairment or combination of impairments which significantly limits [the claimant’s] physical or mental ability to do basic work activities.” [3] At step three, the agency determines whether the impairment which enabled the claimant to survive step two is on the list of impairments presumed severe enough to render one disabled; if so, the claimant qualifies. [4] If the claimant’s impairment is not on the list, the inquiry proceeds to step four, at which the SSA assesses whether the claimant can do his previous work; unless he shows that he cannot, he is determined not to be disabled. [5] If the claimant survives the fourth stage, the fifth, and final, step requires the SSA to consider so-called “vocational factors” (the claimant’s age, education, and past work experience), and to determine whether the claimant is capable of performing other jobs existing in significant numbers in the national economy.
Barnhart v. Thomas, 540 U.S. at 24-25, 124 S.Ct. at 379-80 (fns. & citations omitted); accord, e.g., Talavera v. Astrue, 697 F.3d 145, 151 (2d Cir.2012); Rosa v. Callahan, 168 F.3d at 77; Tejada v. Apfel, 167 F.3d at 774.25
The claimant bears the burden of proof as to the first four steps; if the claimant meets the burden of proving that he cannot return to his past work, thereby establishing a prima facie case, the Commissioner then has the burden of proving the last step, that there is other' work the *402claimant can perform considering not only his medical capacity but also his age, education and training. See, e.g., Barnhart v. Thomas, 540 U.S. at 25, 124 S.Ct. at 379-80.26
C. The Treating Physician Rule
The “treating physician’s rule” is a series of regulations set forth by the Commissioner in 20 C.F.R. § 404.1527 detailing the weight to be accorded a treating physician’s opinion. Specifically, the Commissioner’s regulations provide that:
If we find that a treating source’s opinion on the issue(s) ■ of the nature and severity of your impairment(s) is well-supported by medically acceptable clinical and laboratory diagnostic techniques and is not inconsistent with the other substantial evidence in your case record, we will give it controlling weight.
20 C.F.R. § 404.1527(c)(2); see, e.g., Rugless v. Comm’r of Soc. Sec., 548 Fed.Appx. 698, 699-700 (2d Cir.2013); Meadors v. Astrue, 370 Fed.Appx. 179, 182 (2d Cir.2010); Colling v. Barnhart, 254 Fed.Appx. 87, 89 (2d Cir.2007); Lamorey v. Barnhart, 158 Fed.Appx. 361, 362 (2d Cir.2006).
Further, the regulations specify that when controlling weight is not given to a treating physician’s opinion (because it is not “well-supported” by other medical evidence), the ALJ must consider the following factors in determining the weight to be given such an opinion: (1) the length of the treatment relationship and the frequency of examination; (2) the nature and extent of the treatment relationship; (3) the evidence that supports the treating physician’s report; (4) how consistent the treating physician’s opinion is with the record as a whole; (5) the specialization of the physician in contrast to the condition being treated; and (6) any other factors which may be significant. 20 C.F.R. § 404.1527(c)(2)-(6); see, e.g., Cichocki v. Astrue, 534 Fed.Appx. 71, 74 (2d Cir.2013); Gunter v. Comm’r of Soc. Sec., 361 Fed.Appx. 197, 197 (2d Cir.2010); Foxman v. Barnhart, 157 Fed.Appx. 344, 346-47 (2d Cir.2005); Halloran v. Barnhart, 362 F.3d 28, 32 (2d Cir.2004); Shaw v. Chater, 221 F.3d 126, 134 (2d Cir.2000); Clark v. Comm’r of Soc. Sec., 143 F.3d 115, 118 (2d Cir.1998); Schaal v. Apfel, 134 F.3d 496, 503 (2d Cir.1998).
When a treating physician provides a favorable report, the claimant “is entitled to an express recognition from the [ALJ or] Appeals Council of. the existence of [the treating physician’s] favorable ... report and, if the [ALJ or] Council does not credit the findings of that report, to an explanation of why it does not.” Snell v. Apfel, 177 F.3d 128, 134 (2d Cir.1999); see, e.g., Cichocki v. Astrue, 534 Fed.Appx. at 75; Zabala v. Astrue, 595 F.3d 402, 409 (2d Cir.2010) (ALJ’s failure to consider favorable treating physician evidence ordinarily requires remand pursuant to Snell but does not require remand where the report was “essentially duplicative of evidence considered by the ALJ”); Ferraris v. Heckler, 728 F.2d 582, 587 (2d Cir.1984) (“We of course do not suggest that every conflict in a record be reconciled by the ALJ or,the Secretary, but we do believe that the crucial factors in any determination must be set forth with sufficient specificity to enable [reviewing courts] to decide whether the determination is supported by substantial evidence.” (citations omitted)); Ramos v. Barnhart, 02 Civ. 3127, 2003 WL 21032012 at *7, *9 (S.D.N.Y. May 6, 2003) *403(The ALJ’s “ ‘failure to mention such [treating physician report] evidence and set forth the reasons for his conclusions with sufficient specificity hinders [this Court’s] ability ... to decide whether his determination is supported by substantial evidence.’ ”).
The Commissioner’s “treating physician” regulations were approved by the Second Circuit in Schisler v. Sullivan, 3 F.3d 563, 568 (2d Cir.1993).
D. The ALJ’s Duty To Develop The Record
It is the “well-established rule in [the Second] circuit” that the ALJ must develop the record:
[I]t is the well-established rule in our circuit “that the social security ALJ, unlike a judge in a trial, must on behalf of all claimants ... affirmatively develop •the record in light of the essentially non-adversarial nature, of a benefits proceeding.” Lamay v. Comm’r of Soc. Sec., 562 F.3d 503, 508-09 (2d Cir.2009) (internal quotation marks and brackets omitted) [, cert. denied, 559 U.S. 962, 130 S.Ct. 1503, 176 L.Ed.2d.l52 (2010) ]; accord Butts v. Barnhart, 388 F.3d 377, 386 (2d Cir.2004), [amended on other grounds], 416 F.3d 101 (2d Cir.2005); Pratts v. Chater, 94 F.3d 34, 37 (2d Cir.1996); see also Gold v. Sec’y of Health, Educ. & Welfare, 463 F.2d 38, 43 (2d Cir.1972) (pro se claimant).' Social Security disability determinations are “investigatory, or inquisitorial, rather than adversarial.” Butts, 388 F.3d at 386 (internal quotation marks omitted). “[I]t is the ALJ’s duty to investigate and develop the facts and develop the. arguments both for and against the.granting of benefits.” Id. (internal quotation marks omitted); accord Tejada v. Apfel, 167 F.3d 770, 774 (2d Cir.1999).
Moran v. Astrue, 569 F.3d 108, 112-13 (2d Cir.2009). This duty is heightened when a claimant proceeds pro se, see, e.g., Moran v. Astrue, 569 F.3d at 113; Hamilton v. Colvin, 10 Civ. 9641, 2013 WL 3814291 at *13 (S.D.N.Y. July 23, 2013), but still “applies even where the applicant is represented by counsel,” see, e.g., Eusepi v. Colvin, 595 Fed.Appx. 7, 9 (2d Cir.2014) (ALJ must seek additional record evidence when there are “obvious gaps,” even when represented parties are 'involved); Rivera v. Comm’r of Soc. Sec., 728 F.Supp.2d 297, 321-22, 328-29 (S.D.N.Y.2010).
The ALJ has an affirmative duty to fill any obvious gaps in the administrative record prior to rejecting a treating physician’s opinion. See, e.g., Swiantek v. Comm’r of Soc. Sec., 588 Fed.Appx. 82, 84 (2d Cir.2015) (citing Rosa v. Callahan, 168 F.3d 72, 79 (2d Cir.1999)); Barbera v. Barnhart, 151 Fed.Appx. 31, 33 (2d Cir.2005); Ulloa v. Colvin, 13 Civ. 4518, 2015 WL 110079 at *11 (S.D.N.Y. Jan. 7, 2015).27 “However, ‘where there are no obvious gaps in the administrative record, and where the ALJ already possesses a “complete medical history,” the ALJ is under no obligation to seek additional information in advance of rejecting a benefits claim.’ ” Swiantek v. Comm’r of Soc. Sec., 588 Fed.Appx. at 84 (quoting Rosa v. Callahan, 168 F.3d at 79 n. 5); see also, e.g., Abbott v. Colvin, 596 Fed.Appx. 21, 24 (2d Cir.2015); Eusepi v. Colvin, 595 Fed.Appx. at 9 (for claimant represented by counsel the ALJ must seek additional record evidence only where -there are “obvious gaps”); Tankisi v. Comm’r of Soc. *404Sec., 521 Fed.Appx. 29, 34 (2d Cir.2013) (finding it unnecessary to obtain a treating source opinion where “a voluminous medical record” exists “that [is] adequate to permit an informed finding by an ALJ”).
II. BECAUSE ALJ FRIEDMAN DID NOT SUFFICIENTLY DEVELOP THE RECORD, REMAND IS NECESSARY
ALJ Friedman found that Wilson had the RFC to “perform light work as defined in 20 C.F.R. § 404.1567(b) except he is restricted from performing jobs involving pulmonary irritants.” (See page 14 above.) Wilson argues that ALJ Friedman’s RFC determination for Wilson is contradicted by the medical evidence of record, particularly that Wilson’s pulmonary function test results, “do not support a finding that Mr. Wilson enjoyed an unrestricted capacity for walking.” (Dkt. No. 15: Wilson Br. at 15-16.) Wilson argues that where “ALJ Friedman reviewed the file and cites the FEV1 findings as reflective of normal findings, he impermissibl[y] sets his lay interpretation of the evidence against that of Dr. Naeem, a board certified internist [who] has treated Mr. Wilson for more than ten years.” (Dkt. No. 15: Wilson Br. at 16, record citation omitted.)
In assessing whether a claimant has a disability, the factors to be considered include:
“(1) the objective medical facts; (2) diagnoses or medical opinions based on such facts; (3) subjective evidence of pain or disability testified to by the claimant or other[s]; and (4) the claimant’s educational background, age, and work experience.”
Singleton v. Colvin, 13 Civ. 4185, 2015 WL 1514612 at *12 (S.D.N.Y. Mar. 31, 2015) (quoting Rivera v. Harris, 623 F.2d 212, 216 (2d Cir.1980)); see also, e.g., Sayles v. Colvin, 13 Civ. 6129, 2014 WL 4384133 at *11 (S.D.N.Y. Aug. 28, 2014), report & rec. adopted, 2014 WL 4631202 (S.D.N.Y. Sept. 16, 2014); Rivera v. Comm’r of Soc. Sec., 728 F.Supp.2d 297, 319 (S.D.N.Y.2010).
In determining Wilson’s RFC, ALJ Friedman relied extensively on Wilson’s objective pulmonary function tests (specifically, spirometry tests), interpretations of those tests by Wilson’s doctors and state examiners, and the ALJ’s own interpretation of them. (See pages 16-18 above.) ALJ Friedman referred to five specific FEV1 results and stated that Wilson’s “testing has ranged from 73% to 129% of predicted and normal rates.” (See page 16 above). ALJ Friedman also relied on Wilson’s spirometry results and his doctors’ interpretations of them in determining Wilson’s credibility when he found that Wilson’s symptoms were not substantiated by objective medical evidence. (See page 16 above.)
ALJ Friedman also relied on the spirometry results in determining the weight to be given to the medical opinion evidence in the record. (See pages 16-18 above.) ALJ Friedman gave “great weight” to state agency reviewing physician Dr. Bank-head’s opinion because he “based his opinion on findings from [objective] peak flow testing revealing FEV1 levels in 2012 up to 129% of expected values.” (See page 16 above.) ALJ Friedman gave “some weight” to consultative examiner Dr. Re-van’s opinion as “somewhat consistent with [Wilson’s] objective medical evidence, including FEV1 testing.” (See page 17 above.) ALJ Friedman gave “little weight” to treating physician Dr. Naeem’s opinion because Wilson’s “medical records do not support Dr. Naeem’s opinion” including Wilson’s “normal FEV1 peak flow testing.” (See page 17 above.) ALJ Friedman also gave little weight to treating physician Dr. Husain’s opinion in part because “objective medical evidence, in-*405eluding spirometric testing, reveals that [Wilson’s] conditions, including COPD, are not nearly as limiting as he has alleged.” (See pages 17-18 above.)
There is, however, an obvious gap in the medical record in the form of the pulmonary function tests’ multiple and unexplained predicted normal values for Wilson. Spirometry is an objective form of pulmonary function testing. See 20 C.F.R. Part 404, Subpart P, Appendix 1, § 3.00(A), (E). Two particular measurements are important: “one-second forced expiratory volume (FEV1) and forced vital capacity (FVC).” 20 C.F.R. Part 404, Sub-part P, Appendix 1, § 3.00(E). A person’s reported FEV1 and FVC are gauged in relation to the predicted normal value of each measure for an individual. See 20 C.F.R. Part 404, Subpart P, Appendix 1, § 3.00(E) (triggering use of a bronchodilator “if the pre-bronchodilator FEV1 value is less than 70 percent of the predicted normal value”).28 The predicted normal value for each person is a fixed value based off of a person’s height. See 20 C.F.R. Part 404, Subpart P, Appendix 1, § 3.00(E) (“The pulmonary function tables in 3.02 and 3.04 are based on measurement of standing height without shoes.”); 20 C.F.R. Part 404, Subpart P, Appendix 1, § 3.02(A), Table I (establishing Listed disability for “[c]hronic obstructive pulmonary disease ... with the FEV1 equal to or less than the values specified in table I corresponding to the person’s height without shoes”).29
As opposed to one fixed predicted normal value for Wilson’s FEV1, as many as four different predicted normal values appear in the record. (See pages 6-9 above.)30 It is unclear how these predicted values were determined. Only one of Wilson’s spirometry reports actually records Wilson’s height and weight — Dr. Dobkin’s February 2011 test, which notes them as seventy-four inches and 270 pounds respectively. (See R. 180-81; page 9 above.) The predicted normal value for FEV1 in Dr. Dobkin’s records was 4.26 liters. (See page 8 above.) Dr. Dobkin’s predicted normal value is consistent with the NHANES III Reference Value for a fifty-six year old Caucasian male standing 188 centimeters (seventy-four inches) tall. See NIOSH Division of Respiratory Disease Studies, NHANES III Reference Values (predicted normal FEV1 of 4.27 liters), available at http://www.cdc.gov/ niosh/topics/spirometry/nhanes.html.31 Wilson’s FEV1 was seventy-three percent of predicted normal value on Dr. Dobkin’s February 17, 2011 exam. (R. 181; see page 8 above.)
*406The predicted FEVl values listed for Wilson’s other pulmonary function tests vary, and as a result his reported FEVl percentage varies in both his pre- and post-bronchodilator results:
[[Image here]]
(See pages 6-10 above.)32 Wilson’s FEVl results vary widely as a percentage of his predicted results depending on whether they are calculated based on the predicted values reported in those spirometry results or based on Dr. Dobkiris predicted normal FEVl value for Wilson, which is consistent with the relevant NHANES III Reference Value. (See pages 30-31 above.)
The record contains insufficient information to determine how the other predicted normal values were generated or why they vary, because no height or other information actually was recorded on any of the spirometry reports other than Dr. Dob-kin’s February 17, 2011 report. (R. 180-SI, 184-85; see pages 6-7, 9-10 above.) Moreover, although the 2010 spirometry results from Dr. Naeem that omit Wilson’s height and weight were obtained on the same days as examinations that do note Wilson’s height and weight, Dr. Naeem’s records contain wiidly different heights and weights for Wilson on each occasion. (See R. 198, 201; pages 6-7, 7 n. 11 above.) Finally, neither Wilson’s April 17, 2012 spirometry result nor Dr. Naeem’s examination records from the same day mention Wilson’s height or weight. (See R. 184, 205; pages 9-10 above.) Because Wilson’s predicted normal FEVl value varies greatly without explanation, it is unclear that the measurement of his reported FEVl as a percentage of his predicted normal FEVl has any utility whatsoever.33 There is no evidence in the record indicating that any of the medical experts- were aware of, or adjusted for, the erroneous divergence in predicted normal values. (See R. ISO-82, 184-86,198-99, 201-02, 246.)
It is not the ALJ’s role (nor the Court’s, for that matter) to determine which predicted normal value from the variety of available reference values is correct or how the spirometry results should be interpreted. See, e.g., Calzada v. Asture, 753 *407F.Supp.2d 250, 277 (S.D.N.Y.2010) (“An ALJ must not substitute his‘own assessment of the relative merits of the objective evidence and subjective complaints for that of a treating physician.’”); Melendez v. Astrue, 630 F.Supp.2d 308, 313 (S.D.N.Y.2009) (ALJ obtained testimony of medical expert to interpret pulmonary function tests). Despite the insufficient evidence concerning the divergence in Wilson’s predicted normal values for his FEV1 results, ALJ Friedman did not seek further information from any of Wilson’s doctors or the consulting doctors. (See R. 19-25.) This left ALJ Friedman with an incomplete record on which to base his RFC determination, and the Court, cannot determine whether it is supported by substantial evidence. See, e.g., Corporan v. Comm’r of Soc. Sec., 12 Civ. 6704, 2015 WL 321832 at *21 (S.D.N.Y. Jan. 23, 2015) (“Indeed, the Court cannot ... [decide], whether the ALJ’s decision regarding [plaintiffs] functional capacity was supported by substantial evidence if the determination was based on an incomplete record.”); Stuart v. Colvin, No. 13-CV-04552, 2014 WL 4954487 at *13 (E.D.N.Y. Sept. 30, 2014); Legall v. Colvin, 13 Civ. 1426, 2014 WL 4494753 at *4 (S.D.N.Y. Sept. 10, 2014) (“‘[b]ecause an RFC determination is a medical determination, an ALJ who makes an RFC determination in the absence of supporting expert medical opinion has improperly substituted his [or her] own opinion for that of a physician, and has committed legal error’ ” (citing Hilsdorf v. Comm’r of Soc. Sec., 724 F.Supp.2d 330, 347 (E.D.N.Y.2010))); Rivera v. Comm’r of Soc. Sec., 728 F.Supp.2d at 318-19, 331-32 (legal error in failure to develop record makes substantial evidence inquiry unnecessary). ALJ Friedman thus failed in his “affirmative obligation to fully develop the administrative record,” Calzada v. Asture, 753 F.Supp.2d 250, 269 (S.D.N.Y.2010).
Legal errors regarding the duty to develop the record warrant remand. See, e.g. Rosa v. Callahan, 168 F.3d 72, 79-80 (2d Cir.1999) (Sotomayor, C.J.) (remanding where ALJ failed to fully develop record by neglecting to seek information or explanation to supplement treating physicians “sparse” notes which were “ ‘conclusive of very little’ ”); Elliott v. Colvin, No. 13-CV-2673, 2014 WL 4793452 at *18 (E.D.N.Y. Sept. 24, 2014) (“[W]here the ALJ has failed to fully develop the factual record, the proper remedy is to remand the case for further proceedings.”); Barnwell v. Colvin, 13 Civ. 3683, 2014 WL 4678259 at *12 (S.D.N.Y. Sept. 9, 2014); Oliveras v. Astrue, 07 Civ. 2841, 2008 WL 2262618 at *8 (S.D.N.Y May 30, 2008), report & rec. adopted, 2008 WL 2540816 (S.D.N.Y. June 25, 2008); see also cases cited at page 26-27 above. Because the unexplained error in the predicted normal values for Wilson’s FEV1 creates an obvious gap in the record that ALJ Friedman should have developed, remand is appropriate.34
*408The Court notes that it may be that because Wilson was able to work through January 29, 2012 (when he retired), that his COPD and other ailments did not render him disabled. Thus, on remand it may be that his DIB claim again will be denied. Nevertheless, the Court cannot sustain the ALJ’s determination on the present record.
CONCLUSION
For the reasons set forth above, the Commissioner’s motion for judgment on the pleadings (Dkt. No. 18) is DENIED, and Wilson’s motion for judgment on the pleadings (Dkt. No. 14) is GRANTED to the extent of remanding the case to the Commissioner for further proceedings consistent with this Opinion.

. In March 2012 the Commissioner amended 20 C.F.R. §§ 404.1512 and 416.912 to remove paragraphs requiring an ALJ to recontact a treating physician under certain circumstances. See 20 C.F.R. §§ 404.1512(e)(1) and 416.912(e)(1) (effective 6/13/11 to 3/25/12); see also Ulloa v. Colvin, 2015 WL 110079 .at *11 n. 6.

. Although height is the principle measurement needed to calculate FEV1 for the purposes of disability determinations, see 20 C.F.R. Part 404, Subpart P, Appendix 1, § 3.02, the most accurate predicted normal values require information about a person’s age, gender, height and race or ethnicity. See National Institute for Occupational Safety & Health ("NIOSH”) Spirometry Training Guide § 6-1 (2003) ("to optimally interpret spirometry results (observed values), you must first know the [person’s] age, height, gender, and race or ethnicity.”). NIOSH Division of Respiratory Disease Studies, NHANES III Reference Values, available at http://www.cdc.gov7niosh7topics7spirometry 7nhanes.html (tables based on gender, race or ethnicity, age, and ultimately height).
. The Commissioner concedes that the "predicted FEV1 values contained in each report were not identical.” (Dkt. No. 19: Gov’t Br. at 20.)
. Wilson's race and ethnicity are unclear from the record. (Compare R. 179 (“Black”), with R. 181, 184, 185, 186 (“Caucasian”).)
. For each date listed in the table, the first line contains pre-bronchodilator results, while the second line contains post-bronchodilator results. ALJ Friedman made no distinction between pre-bronchodilator and post-bronchodilator, results in citing to the FEVl results or théir .percentages in relation to the predicted normal value, citing a mix of both. (See R. 23.)
. Reported FEVl as a percentage of predicted normal FEVl can provide medical experts with a rough measure of the severity of a person's COPD. See, e.g., Charles T. Hall, Soc. Sec. Disab. Prac. §§ 7:14 (quoting the Global Initiative for Chronic Obstructive Lung Disease ("GOLD”) criteria for evaluating COPD using FEVl relative to predicted normal value), 8:25 ("Stage II: Moderate COPD — Worsening airflow limitation (FEV17FVC < 70%; 50% < FEVl < 80% predicted)”) (practice form).
. The Court need not address Wilson's other arguments challenging ALJ Friedman’s decision. (Diet. .No. 15: Wilson Br. at 16-21.) Because of ALJ Friedman's legal error in failing to develop the record with respect to the variance in the predicted normal values for Wilson’s FEV1 results, the Commissioner necessarily will have to reassess both Wilson’s RFC and credibility, particularly since ALJ Friedman relied extensively on the FEV1 results in evaluating Wilson's credibility and weighing the medical opinion evidence (see pages-16-18 above). Therefore, it is unnecessary to consider-whether ALJ Friedman’s decision was otherwise supported by substantial evidence. See, e.g., Ulloa v. Colvin, No. 13 Civ. 4518, 2015 WL 110079 at *15 (S.D.N.Y. Jan. 7, 2015) (" ‘[0]nly after finding that the correct legal standards were applied should the Court consider the substantiality of the evidence.’ ”); Jackson v. Colvin, 13 Civ. 5655, 2014 WL 4695080 at *21 (S.D.N.Y. Sept 3, 2014) ("Given that the Court recommends remand for further development of the rec*408ord, the Commissioner will be required to reassess both [plaintiff's] credibility and [his] RFC in light of the new evidence.”); Serrano v. Colvin, 12 Civ. 7485, 2014 WL 197677 at *18 (S.D.N.Y. Jan. 17, 2014); Rivera v. Comm’r of Soc. Sec., 728 F.Supp.2d 297, 331 (S.D.N.Y.2010) ("Because I find legal error requiring remand, I need not consider whether the ALJ’s decision was otherwise supported by substantial evidence.”)
